Perl: fixed syntax usage for C preprocessor directives.

As per perlxs, C preprocessor directives should be at the first
non-whitespace of a line to avoid interpreting them as comments.

#if and #endif are moved so that there are no blank lines before them
to retain them as part of the function body.
